CLAY-CLEANER.

Specification of Letters Patent.

Patented Apr. 20, 1215.

To all whom it may concern:

Be it known that we, BERNARD JAG UART and JOHN V. V. BOORAEM, both citizens of the United States, and residents, respectively, of South River, in the county of Middlesex and State of New Jersey, and the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Clay-Cleaners, of which the following is a specification. 7

This invention relates to clay cleaners, and particularly to improvements therein, the object of which is to bring about a cutting of the clay without clogging of the machine, due to the pebbles or stones in the clay.

Heretofore, in the use of clay cleaners, the knives rotating beneath the hopper containing the clay with the stones therein, caused the stones to be collected against one end of the hopper, which were thereby brought into the path of the knives on the continual rotation of the same. This resulted in the breaking and dulling of the knives, and the clogging of the machine.

The object of the invention is to provide means which will permit the stones to be taken away and put into a position where they may freely move, and thereby not act in a clogging manner on the knives.

For this purpose our invention consists of an extension to a hopper of a clay cleaner, which has an open top to permit the free movement of the clay .and stones therein, and also in the combination therewith of a sliding door, so as to permit the removal of the clay and stones contained in the extended open top part.

In the accompanying drawings, Figure 1 is a plan view of a clay cleaner embodying our invention, with only the parts material to the understanding of the invention shown therein, Fig. 2 is a front view of the door as applied to the extension of the hopper, and Fig. 3 is a vertical longitudinal section of a part of the hopper and the extension.

Similar characters of reference indicate corresponding arts throughout the various figures of the rawings.

Referring to the drawings, and more particularly to Fig. 1, the frame 10 is provided with the well known supports 11, which have suitable cross-bars 12 which support the necessary mechanism for operating the clay cleaner, and which is not shown as it forms no part of this invention. The clay cleaner is provided with the well known knife carrier 13, with knives 13 arranged radially as is well known, and which knives pass underneath the hopper l4, and thereby shave OK as much of the clay in the hopper as 1s necessary and desirable in one rotation. The hopper 14 is provided with end walls 15 and 16, and arcuate walls 17 and 18, substantially concentric, as is shown in Fig. 1. As the carrier 13 with its knives rotates, a part of the clay with the stones and pebbles therein is forced against the end wall 16 and gathers at that place due to the weight of the clay in the hopper, causing a considerable clogging of the pebbles and thereby great pressure on the knives, as they are rotated and strike the clay and pebbles. To prevent this clogging and consequent in- ]ury to the knives, an extension is provided which consists of side walls 20 and 21 contaming guide ways 22 for a sliding door 25 to be moved therein. This sliding door is provided with a V-shaped support 26 .which is pivoted to a link 27 which is in turn pivoted to a cross-bar 29, having a handle 30, which cross-bar 29 has its other end pivoted at 33 to a supporting link 28 which is pivotally secured to the frame 12 at 31.

To permitthe pebbles in the clay to pass into the extension, the lower end of the hopper wall 16 is provided with an opening 35. When the knife strikes a pebble, it gradually moves it along the length of the hopper, until it reaches the opening 85 of the wall 16, and then forces the pebble through the opening into the extension or separate compartment and against the door 25. But while these same pebbles, in the event that the wall of the hopper extended all the way down to the knife, might clog the knives, the pebbles now in the extension with the open space above it, will not clog it, and since they are free to move upwardly, the striking knife will not be clogged. A certain portion of the clay, of course, is taken along in the movement of the pebbles and gathers in the extension. When a suflicient number of pebbles have accumulated in the extension, the door 25 is manually operated and the pebbles removed. The extension is shown outside of the hopper, but we do not wish to limit ourselves thereto, since the feature of our invention is to have i a compartment in which the pebbles are not subjected to the Weight ofthe material in the hopper.

We have shown an embodiment of our invention, but it is clear that changes may be made therein, without departing from the spirit of the invention. 1

We claim:

1. In a clay cleaner, a hopper for material to be cut, and a stone compartment open at its top for escape of material over the Walls 'thereofihaving a front wall of a height approximately that of the normal height of the material in the hopper, to create a back pressure by means of the weight of the material in the compartment,

height of the material in the hopper, an extension or compartment in communication with the main hopper by means of said opening, and having an open top, and a manually operated door on the extension for permitting the discharge of the contents thereof and for creating a variable back pressure by means of the weight of the material in the compartment, said door being of approximately the same height as the normal height of thematerial in the hopper.

3. In a clay cleaner, a hopper for the material to be out having a wall with its lower end distant from the knives and extending below the material in the hopper, and an open-top extension protected by the Wall from the weight of the clay in the hopper,

and manually-operative means for discharg- 7 ing the material in the extension for creat mg a variable back pressure by means of the welght of the material 1n the compartment, said means being of approximately.

the same height as the normal height of the material in the hopper. 1

4. In a clay cleaner, a hopper of arcuate shape rotating knives and table below the same forcing pebbles and material against second wall beyondthe first, and manually-.

operative discharge means for the matter containedbetween the wall of the hopper having the openingand the wall extending in proximity to the knives, said second Wall being of approximatelythe same height as the normal height of the material in. the hopper for creating. a back pressureiby means or" the Weight of the materialin the compartment. 1 '7 V In testimony, that We claim the foregoing as our invention, We have signed our names in presence of two subscribing witnesses.
